NORTHERN WINTER: north to southern Baja California, southern Sonora, Gulf Coast, and Virginia, south through most of the breeding range. In the U.S., the highest winter densities occur in southern Louisiana bayous, around the mouth of the Mississippi River, especially the Delta NWR, and to a much lesser extent in Florida (Root 1988).
